Preparation guide

  1. Record the power-button indicator at the event. The guide identifies steady on as on, slow blinking as sleep, and off as off or hibernation; off alone does not distinguish those last two states.

  2. Review Windows power settings and the configured power-button/lid behavior without changing a managed plan. The computer’s actual settings determine the comparison; a closed lid is not proof it slept.

  3. Save work, safely remove the dock/peripherals, and choose Windows Start → Power → Sleep when available. Record the indicator and whether an ordinary brief power-button press resumes work.

  4. If safe, compare another ordinary event using the documented dock setup or a later direct baseline. Keep the selected power plan and workload constant. Record each actual event instead of repeatedly forcing failure.

  5. If a normal resume fails and a forced shutdown is needed, stop repeated testing. Retain indicator, power source, accessory state and backup availability for Lenovo/IT.

Original schematic mapping official Vantage availability to scan scope and result, alongside power-indicator meanings used in a resume log.

Check the result

  • Indicator off is not labeled uniquely as shutdown.
  • Events are recorded without forced repeated failures.
Stop conditions
  • Stop using and charging equipment with swelling, casing separation, smoke, a burning smell or suspected battery damage. Do not open or press on it.
  • Set damaged accessories aside. Do not open mains adapters or force connectors.
  • Do not erase, reset, flash firmware or bypass a lock as a default diagnostic step.
